Millimeter-wave integrated circuits with gate lengths as short as 35 nm are demonstrating extremely low-noise performance, especially when cooled to cryogenic temperatures. These operate at low voltages and are susceptible to damage from electrostatic discharge and improper biasing, as well as being sensitive to low-level interference. Designing a protection circuit for low voltages and tempera...

Satellite-cellular convergence promises to enable higher millimetre-wave bandwidth (data rate); beamformed better signal alignment (higher system efficiency); multi-connectivity data rates); and new use cases (verticals). Harnessing these opportunities will depend on overcoming challenges spanning shorter distance/reduced coverage component complexity; construction of antenna array over-the-air...

Abstract : Microstrip antennas or patch antennas are popular for their attractive features such as low profile, low weight, low cost, ease of fabrication and integration with RF devices. Micro strip antennas have been found favorable because they are inexpensive to manufacture and compatible with monolithic microwave integrated circuit designs (MMIC). They are usually employed at UHF and higher...

In this paper, a novel approach has been suggested to obtain an improved spurious-free window for dielectric resonator in microwave integrated circuit environment. In microwave integrated circuit environment, the dielectric resonator placed on a thin dielectric substrate gets located asymmetrically with respect to its shielding enclosure. A reduced separation in frequencies (mode separation) is...

A complete procedure for the design of W-band low noise amplifier in MMIC technology is presented. The design is based on a simultaneously power and noise matched technique. For implementing the method, scalable bilateral transistor model parameters should be first extracted. The model is also used for transmission line utilized in the amplifier circuit. In the presented method, input/output ma...

In this paper, we demonstrate a robust design of Monolithic Microwave Integrated Circuits (MMIC) using Taguchi Method. In accordance with Taguchi Method, noise factors, which are uncontrollable sources of variation, and control factors, which are available to control both the deviations and the mean-values by circuit designers were assigned to an orthogonal array. We simulated radio frequency (...

The development of numerical techniques now permits us to analyze complex structures such as dielectric resonator filters and planar passive elements for coplanar monolithic microwave integrated circuits. In this paper, we describe a novel method for designing dielectric resonator filters. Then a Chebychev band pass filter is designed by coaxially placing high-Q TM01Q dielectric resonators ...

A conventional active phased array antenna (APAA) for a military purpose is composed of modules each of which includes a radiator, a high power amplifier (HPA), a low noise amplifier (LNA), a phase shifter and combiners on a printed circuit board (PCB). Therefore, such a APAA is thicker than the longitudinal size of the PCB. Several attempts of planar APAAs were proposed to overcome the disadva...
